So, thank you so much for everyone who answer my question. so the problem was when i update the data, system only detect "kondisi[]" and "keterangan[]" as an array because i use this "[]" for both of it, so i just have to add "[]" in the end of every name in html form / views. so system will detect every input as an array. i hope you understand what i'm saying, sorry for my bad english. thank you this case is closed :)
